Signature Sdk
=============

[](#signature-sdk)

Signature SDK is a framework-agnostic PHP library that provides secure request signing and verification logic. It is the core signing engine used by [laravel-signature](https://github.com/mitoop/laravel-signature).

Requirements
------------

[](#requirements)

- PHP 7.4 or higher
- OpenSSL extension enabled

Installation
------------

[](#installation)

Install via Composer:

```
composer require mitoop/signature-sdk
```

🚀 Quick Start
-------------

[](#-quick-start)

Signature SDK supports the following signature methods: **SHA256-RSA2048**, **SHA256-HMAC**, and **ED25519**

#### 🔐 Using RSA Signature:

[](#-using-rsa-signature)

```
use Mitoop\SignatureSdk\Client;
use Mitoop\SignatureSdk\RequestSigner;
use Mitoop\SignatureSdk\Signers\RsaSigner;

$privateKey = 'your_rsa_private_key_string';
$publicKey = 'plat_rsa_public_key_string';

$signer = new RsaSigner($privateKey, $publicKey);

$requestSigner = new RequestSigner(
    mchid: 'your_merchant_id',
    appid: 'your_app_id',
    signer: $signer,
    platformPrefix: 'MP' // Paltform prefix
);

$client = new Client(
    config: [
        'base_url' => 'https://api.example.com',
    ],
    signer: $requestSigner
);

$response = $client->post('/v1/pay', [
    'amount' => 100,
    'currency' => 'USD',
]);

$data = json_decode((string) $response->getBody(), true);

print_r($data);
```
